9.Background
Inductive Coupling: good coupling between two coils, a transmitter coil and a receiver coil. An alternating current in the transmitter coil generates a magnetic field which induces a voltage in the receiver coil. This voltage can be used to power a mobile device or charge a battery. It is ideal for wireless charging transmitter coil assembly and increase the charging efficiency.
10.Features
Wireless charging transmitter coil assembly (Tx - coil)
Litz wire winding Shield by Ni-Zn ferrite material
Compliance with Qi standard of WPC
11.Applications
Mobile Phones
Battery or battery Chargers
Cameras
MP3 /PMP
MID's
Hand Held Devices
Gaming devices
